Figure Lengend Snippet: (A) RoMa prototypes with PTFE sleeves. (B) Assembled and disassembled PTFE stopper equipped with a safety valve. (C) Large RoMa prototype equipped with PTFE stopper and stop device. (D) Operating regimes of the stopper: (I) gas purge (blue arrows). (II) Equilibrium. (III) Exchange surface saturation and thermal expansion of the stopper (red arrows). (IV) Valve opening ( P > 0.15 bar above P atm ).

Article Snippet: A commercially available PTFE stopper (COWIE, item #010.229), to be placed on the top outlet of the condenser, was modified by inserting a safety valve in its center, reminiscent of a pressure cooker system.

Figure Lengend Snippet: UV–visible (A) and normalized emission spectra (B) of ZnPc - and Ir-ZnPc -loaded NCs in H 2 O (λ exc = 620 nm). Inset: Photographic images of NCs in daylight (left) and in the dark (right) upon irradiation with a blue light laser (465 nm). (C, D) Photogeneration of superoxide and hydroxyl radical by ZnPc and Ir-ZnPc . Increase of the fluorescence spectra emission of DHR123 (C) or HPF (D) upon photoirradiation of ZnPc , Ir-ZnPc , and methylene blue ( MB ) or without any compound (DHR123 or HPF alone) at 620 nm (130 mW/cm 2 ) in PBS (0.2% DMSO). DHR123 and HPF fluorescence were excited at 500 and 490 nm, respectively. (E, F) Single confocal planes of HeLa cells incubated with the encapsulated and free forms of the compounds for 30 min at 37 °C. In (E, F), left-hand side shows the merge of bright-field and fluorescence images and right-hand side shows the fluorescence images of the compounds. (E) ZnPc-NCs (top) and ZnPc (bottom). (F) Ir-ZnPc-NCs (top) and Ir-ZnPc (bottom). Images were acquired by irradiation with a 633 nm laser line. Scale bar: 20 μm. Adapted from ref

Article Snippet: The data interval was 1 nm, and the integration time was 0.7 s. All measurements were carried out using a Hellma 1.5 mL PTFE-stoppered fluorescence quartz cuvette (4 clear windows) with a 1 cm path length. (1) Evaluation of superoxide anion radical generation using DHR123 DHR123 (10 μM) was added to a solution of the corresponding studied compound (10 μM) in phosphate-buffered saline (PBS) containing 2% DMSO.
